报告摘要:In this talk, we introduce the complex symmetric  weighted composition operators on the Hilbert space $H_{s}$ of holomorphic functions over the open unit ball $\mathbb{B}_{n}$ with reproducing kernels $K^{s}_{w}=(1-\langle z,w\rangle)^{-s}$, where $s\in\mathbb{N}^{+}$. First,  we completely characterize complex symmetric weighted composition operators with respect to two important conjugations $J_V$, $J_\sigma$, which include Hermitian weighted composition operators and normal weighted composition operators appeared in \cite{[Le]}. Surprisingly, they are essential representatives of general conjugations with the form $C_{\psi,\varphi}J$, where $C_{\psi,\varphi}$ is unitary and $J$-symmetric. Indeed, this kind complex symmetric weighted composition operators are classified into two classes. The size estimates and some other properties of this kind complex symmetric weighted composition operators are obtained. Finally, involutive weighted composition operators on $H_{s}(s>0)$ are completely characterized too. As an application, we construct conjugations for the involutive composition operators.
